Building site waste
This waste comes from any kind of building site (construction, renovation, demolition and decontamination).
Waste can be divided into three categories:
• Inert waste (soil, rocks, concrete, road demolition materials, construction materials)
• Non-hazardous waste (common industrial waste, wood, dry wall, metals, plastics)
• Hazardous waste (aerosols, oil, asbestos, paint, polluted soil, tar and related products, hydrocarbons and other related products, batteries, accumulator, treated wood and any product generated by treating wood, packaging tainted by hazardous products)
The framework directive, agreed in 2008, requires a 70% recycling goal in weight for non-hazardous waste from the construction and civil engineering sector by 2020.
Knowledge of the mix of skills required is necessary to handle the recovery of the variety of wastes. SITA offers a global approach to managing construction site waste for the client:
Collection and sorting:
- Access to appropriate collection facilities
- Sorting at source (waste sorting training, consulting on recovery streams…)
For inert waste:
Preparing the inert waste to be reused for backfilling or recycling at dedicated facilities.
For non-hazardous waste:
- Extraction and recycling of reusable materials (plastics, metals, cables, glass, palettes, etc)
- Energy recovery.
- Treatment of non-reusable waste in non-hazardous waste recycling centres and inert waste recycling centres.
For hazardous industrial waste:
- Stabilising and sending to landfill
- Energy and material recovery in cement kilns
- Special incineration as a treatment and recovery process
- Solvents and fuel regeneration
250 million tonnes of waste generated by the construction and civil engineering sector
30% of the global waste, across the board, is produced by the construction and civil engineering sector
40 million tonnes of waste come from the building sector
- FAYAT’s global managing of construction site waste
SITA and the FAYAT group agree on a national framework contract for the management and the recovery of waste on worksites at the following companies: Razel Bec, Cari, Fayat TP, Satelec, Nord France Construction, SEG-Fayat, SEFI-INTRAFLOR, FRANKI FONDATION, Sols & Fondations, Sotraisol.
As stated in this contract, SITA will:
- advise and organise sorting and temporary storage of the waste in situ,
- coordinate collection,
- recover and handle inert, hazardous and non-hazardous waste.
- Recydem – Lourches (Nord): mineral waste recovery centre
SITA can process 250,000 tonnes a year and has access to a recycling process dedicated to construction and deconstruction waste on the Eco-hub RECYDEM in Lourches (a specialist in managing and recovering mineral waste).
Once transformed, the recycled mineral materials are routed to the construction and civil engineering sector to be used for backfilling and road building as an alternative to natural materials. A special treatment is necessary for the recovery of plaster mixtures.
